Groups of Vascular Plants Vascular plants: divided into 3 smaller groups Angiosperms- Flowering plants Gymnosperms- cone bearing plants Pteridophyte-ferns ****Possible extra credit**** Vascular plants: divided into 3 smaller groups Angiosperms- Flowering plants Gymnosperms- cone bearing plants Pteridophyte-ferns ****Possible extra credit****
Vascular Plants ~270,000 kinds of vascular plants in the world Vascular- means having tubes. Tubes carry water and food to all parts of the plant. (The tubes can be compared to plumbing in a house.) Can be taller than nonvascular plants because of these tubes. ~270,000 kinds of vascular plants in the world Vascular- means having tubes. Tubes carry water and food to all parts of the plant. (The tubes can be compared to plumbing in a house.) Can be taller than nonvascular plants because of these tubes.
Vascular Plants Made of three systems- roots, stems, and leaves Roots- anchor the plant in the ground Absorb water and nutrients from the soil Stems- connect the roots and the leaves Carry water and food. Keeps plant standing straight up Made of three systems- roots, stems, and leaves Roots- anchor the plant in the ground Absorb water and nutrients from the soil Stems- connect the roots and the leaves Carry water and food. Keeps plant standing straight up
Parts of Vascular Plants Leaves- like a factory, make food and give off oxygen. Why do we need Oxygen? Chloroplasts- contain chlorophyll. (what makes plants green) It is a green substance that absorbs sunlight. Sugar or glucose in plants is food for the plant. Leaves- like a factory, make food and give off oxygen.

Photosynthesis- How plants make food?
Nonvascular Plants Nonvascular Plants- nonvascular means without tubes. Do not have tubes to carry water and food to parts of the plant. Absorb water directly, like sponge These plants are small and usually not very tall Plants in this group are called bryophytes Nonvascular Plants- nonvascular means without tubes. Do not have tubes to carry water and food to parts of the plant. Absorb water directly, like sponge These plants are small and usually not very tall Plants in this group are called bryophytes
Bryophytes Grow in damp shady places Grow close to the ground- absorb water nutrients from surrounding Do not have real roots Have rootlike parts- anchor them to ground Leaflike parts- make food Reproduce by spores 3 groups- mosses, liverworts, and hornworts Grow in damp shady places Grow close to the ground- absorb water nutrients from surrounding Do not have real roots Have rootlike parts- anchor them to ground Leaflike parts- make food Reproduce by spores 3 groups- mosses, liverworts, and hornworts
Liverworts and hornworts grow in damp forests Mosses- grow where it is moist, everywhere we see them Liverworts and hornworts grow in damp forests Mosses- grow where it is moist, everywhere we see them
Liverworts
Hornworts
Fungi Fungi- organisms that absorb food and can’t move about Used to be classified in plant kingdom Stiff cell walls let them grow upright Cells lack chloroplasts- so cannot make their own food. 3 groups- mold, mushrooms, and sac fungi Fungi- organisms that absorb food and can’t move about Used to be classified in plant kingdom Stiff cell walls let them grow upright Cells lack chloroplasts- so cannot make their own food. 3 groups- mold, mushrooms, and sac fungi
